Brillouin lasing in coupled silica toroid microcavities
Yoshihiro Honda, Wataru Yoshiki, Tomohiro Tetsumoto +4
We demonstrate stimulated Brillouin scattering (SBS) lasing in a strongly coupled microcavity system. By coupling two silica toroid microcavities, we achieve large mode splitting o…
The effect on Kerr comb generation in a clockwise and counter-clockwise mode coupled microcavity
Shun Fujii, Atsuhiro Hori, Takumi Kato +5
We study the impact of inherent mode coupling between clockwise (CW) and counter-clockwise (CCW) modes on Kerr comb generation in a small whispering-gallery mode microcavity. Our n…
All-optical switching using Kerr effect in a silica toroid microcavity
Wataru Yoshiki, Takasumi Tanabe
We demonstrate experimentally an all-optical switching operation using the Kerr effect in a silica toroid microcavity. Thanks to the small mode volume and high quality factor of th…
Add-drop system for Kerr bistable memory in silicon nitride microrings
Wataru Yoshiki, Takasumi Tanabe
We numerically studied the required conditions for achieving a memory operation based on Kerr bistability in the presence of the thermo-optic effect in silicon nitride microring ca…
Rigorous analysis of bistable memory in silica toroid microcavity
Wataru Yoshiki, Takasumi Tanabe
We model the nonlinear response of a silica toroid microcavity using coupled mode theory and a finite element method, and successfully obtain Kerr bistable operation that does not…
Polygonal silica toroidal microcavity for controlled optical coupling
Takumi Kato, Wataru Yoshiki, Takasumi Tanabe
We fabricated polygonal silica toroidal microcavities to achieve stable mechanical coupling with an evanescent coupler such as a tapered fiber. The polygonal cavity was fabricated…
